PORTABLE ELEVATOR.

Specification of Letters Patent.

Application filed November 4, 1909. Serial No. 526,1?9.

To all whom t may concern Be it known that I, JOHN VViLLrAM A sH- woRTH, of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvements in Portable Elevators, whereof the following is a specification, reference being had to the accompanying drawings.

My improvement is particularly adapted to receive grain from an ordinary Awagon and convey it into a railroad car, although, of course not limited to such use.

As hereinafter described, my invention includes a. truck having' supporting wheels upon which it may be transported, and including a standard provided at its top with a swivel connection arranged to support an elevator including an endless belt and a casing for the same, having at its outlet end au adjustable discharge chute and pivotally connected at its inlet end with a feeding conveyer, including an endless belt, a cas` ing and a hopper for the same. Said standardy is connected with said truck by a cradle frame arranged to support said conveyor and elevator when folded thereon for trans portation; `ind said truck is provided with chain driving mechanism operatively connected with said endless belt.

My invention includes means for longitudinally adjustingA said elevator with respect to its swivel connection with said truck, and, the various novel features of .construction and arrangement hereinafter described.

In the drawings :--Figure I is a perspective view of an elevator conveniently ein bodying my improvementand including a doubler tubular casing elevator and feeding .conveyor folded for transportation. Fig. II 1s a perspective view showing said elevator arranged for operation. Fig. III is a fragmentary transverse sectional view of the form of feeding conveyer and elevator boot shown in Figs. I and II. Fig. IV is a perspective view of a modified form of my invention including aA single tubular casing conveyer. Fig. V ,is a fragmentary plan view showing the chain driving mechanism carried by' the truck. Fig. VI is a perspec tive view showing a modified form of my invention including a conveyor with an open casing folded fortransportation. Fig. VII is a perspective view of the form of my in vention shown in Fig. VI, butarranged for operation. Fig. VIII isa longitudinal seci tional viewof the boot and a portion of the conveyer indicated in Figs. VI and VII.

Yatented Dec. 2e, lieux.

Fig. IX is a fragmentary longitudinal sectional view of the conveyor showing its adjustable pivotal connection with the truck standard. Fig. X is a transverse'sectional view of the conveyor and its pivotal support as shown in Fig. IX. vF ig. XI is an inverted fragmentary sectional view of the adjustable pivotal connection shown in Figs. IX and X.

The truck comprises thebody frame 1 provided with the supporting wheels 2 and having the standard 3 connected with said frame 1 by the cradle frame 41. Said standard 3 is provided at its top with the bearing 6 for the swivel connection which as shown in Figs. IX, X and XI includes the shaft 7 mounted to turn in said bearing 6 and hav ing the yoke 8 carrying the shaft 9 eXtending through the roller frame 10 and having the rollers 11 at the opposite ends of said shaft` 9 upon which the elevator is tiltably supported. Said roller frame 10 is provided with the rollers 13 which with the rollers v 1l are arranged to traverse the channels 14 which are attached to the bottom of the oonveyer which may be longitudinally ad -justed with respect to said pivotal connection by mea-ns of the crank shaft 15 having 4the operating handle 16 and ratchet wheel 17 in operative relation witli the spring pressed pawl 18; said shaft 15 being operatively connected with said roller frame 10 by the flexible connector 2O which extends around the sheave 21 on saiplyframe 10 and has' its o-pposite ends wrappedupon said shaft 15. It is to be understood with refer ence to Fig.: IX that the elevator may be lowered longitudinally with respect to said pivotal connection to the extent determined by said flexible connector 20 and may be longitudinally shifted in either direction by rotation of said shaft 15.

length of the chain 64, and is so effected to leave said chain in operative relationvv Figs I and II the swivel shaft 7 depends from the yoke frame 24 which rigidly connects the parallel tubular casings Q5 of the- 0f course, such adjustment of the elevator is limited by the" double conveyor' including two. pairs of` tubes, alsov rigidly cross connected by the bars 26 and 27, the latter carrying the strut 28, whereby the conveyer may be braced in adjusted position in connection With the bracket 29 extending from the truck body frame 1.' Said double tubular casing con veyer shown in Figs. I and II is provided at its upper end with adjustable discharging chutes l and is pivotally connected at its lower inlet end with the feeding conveyer shown in section in Fig. III including the endless belt 34 in the casing having the hopper 35 to receive the material which is conveyed by said belt 34 from said casing 35 into the oppositely inclined ports 39 of I 15, theelevator boot communicating with the respective tubular casings 25 containing the endless belts Whose opposite parallel flights are supported at the ends of said tubes 25 by sprocket Wheels having respective shafts 4l and 42. Said shafts 42 are provided with sprocket Wheels 43 for cony nection with the driving chains 44, Which are operated by the sprocket Wheels 45 on the counter-shaft 46 journaled in bearings 47 on the conveyer tubes 25. Said driving belts 44 are conveniently provided With tightening devices including brackets 48 provided With the sheaves 4.9 supported by the yoke 50. y

As shown in Fig. III the endless belt 34 is supported at its Junction with the elevator boot by the sprocket Wheels A53 upon the shaft 55; the opposite end of said casing 35 being provided with a similar shaft and sprocket wheels adjustably supported in the bearings 56. Said shaft 53 is provided eX- teriorv to said casing 35 with the sprocket wheel 58 by Which said chain 34 is driven.

As shown in Fig. II said sprocket Wheel 58' is connected by the chain 59 with the sprocket Wheel 60 on the said counter-shaft 49. Said shaft 46 has the sprocket Wheel 63 connected by the chain'64 With the sprocket wheel 66 of the chain driving mechanism carried by the truck body frame l.

As shown in Fig. V the chain driving mechanism carried by the truck frame l includes opposite counterpart chain Wheels 66 on respective counter shafts 67'journaled in eig,

bearings 69 and having their opposite ends 70 squared or otherwise fitted to be turned by a -crank or other convenient means. Moreover, said shaft-s 67 are provided With beveled gears 71 in mesh With beveled gears 72 carried by the main shaft 73 supported in the bearing 74 on said truck body frame 1; said shaft 73 carries the driving sprocket Wheel 76 for operative connection with a inotor. Said Wheel 76 is loose on said shaft 73, but may be operatively connected therewith by thc clutch 77 controlled by the hand lever 7 8; said shaft 7 El is also provided with the sprocket wheel 79 and it is to be understood that either al" said' sprocket Wheels (3(3 or 79 shown in Fig. Y :nay be operatively i :Loses a4- 'a single pair of tubes 85 connected with a boot 86 upon one side thereof.

T he forni of my invention shown in Figs. VI, VII and VIII includes a single conveyer having the endless belt 87 extending in the open casing and supported at the opposite ends thereof upon the shafts 89 and 90, the latter being provided with adjustable bearings 91. Said endless belt 37 is operatively connected by the chain 98 with the endless belt'94 extending in the b'oot coinprising the casing 95 having the hopper 96 which is conveniently formed as indicated in F Vil by movable leaves`98 connected With said raising 95 by the hinges 99. Said belt 94 is supported at its opposite ends by the sprocket -Wheel 100 respectively supported by the shafts 101 and 102 the latter being provided with the adjustable bearings 103 indicated in Fig. VII.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth as it is obvious that various modifica-tions may be inade therein Without departing from the essential features ofA my invention as defined in the ap pended claims.
